Analysis of Iron Core in Transformer
The core is the basic absence of power transformers, consisting of core laminations, insulating parts and core structural parts. The core body is composed of magnetic steel strips with high magnetic permeability. In order to enable different windings to induce voltages proportional to the number of turns, the magnetic fluxes of the two windings are required to be equal. This requires a core made of materials with high magnetic permeability in the windings, so that all magnetic fluxes are linked in the core and the two windings as much as possible, and the magnetic fluxes linked with only one winding are as few as possible.

Several major maintenance methods and key points of isolation transformer
Isolation transformer refers to the input winding and output winding with electrical isolation of the transformer, the isolation transformer to avoid accidental contact with the charged body at the same time, the isolation of the transformer is to isolate the primary secondary winding coil respective current. Early for European countries in the power industry, widely used in the electronics industry or industrial and mining enterprises, machine tools and mechanical equipment in the general circuit control power supply, safety lighting and indicator power supply.

Analysis of Ordinary Faults of Micro Transformer
Micro transformer mainly refers to the following single-phase 20kva, three-phase 50kva transformer, which is characterized by small transformer shape, low cost, less line. Micro-transformers are commonly used equipment in factory electrical control systems. Today, leading transformer manufacturers have to analyze the common faults of micro-transformers.
